I don't know if this is a 4.13 thing, a server thing, or my connection, but yesterday I spawned beside myself
I have had a wretchedly bad connection this month for some reason,

, So bad that I have been unable to play,

,so that may be the cause?, but I have never seen that happen before.
(Sorry SVK, congrats =irss=drawer65)
Janosch said "apparently player aircraft that should be removed (e.g. after landing & hitting refly) can somehow leave an unoccupied static plane behind (!). It's not just a graphic bug, these ghost planes, although rare, are very real and solid".
We noticed that on the SkiesofFire server, and found if when landed, the player puts chocks on, it solves the problem, or seems to.
